1836-22-2 Usage
Uses
Used in Textile Industry:
AZOCAL A is used as a dye for wool and silk, providing a vibrant color to these materials. Its ability to bind with the fibers ensures good fastness properties, making it a popular choice for this application.
Used in Leather Industry:
In addition to textiles, AZOCAL A is also used for leather dyes. Its compatibility with leather materials allows for the creation of colored leather products with good colorfastness.
Used as a Pigment:
Due to its color and stability, AZOCAL A can be used as a pigment in various applications, adding color and vibrancy to different products.
Standard:
The fastness properties of AZOCAL A are measured according to various standards, including ISO and AATCC. The ironing fastness is rated at 3 on the ISO scale and dry 2, wet 5 on the AATCC scale. The light fastness is rated at 6-7 on the ISO scale and 6 on the AATCC scale. The fulling, perspiration, soaping, water, alkali, and acid fastness are also rated accordingly, ensuring that the dye meets industry standards for performance and quality.

Check Digit Verification of cas no
The CAS Registry Mumber 1836-22-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1836-22:
(6*1)+(5*8)+(4*3)+(3*6)+(2*2)+(1*2)=82
82 % 10 = 2
So 1836-22-2 is a valid CAS Registry Number.
